Write an equation of the line in point slope form that passes through (-16, 8) and (4,-2)
Feliz [49]

When the reference point is used in the point-slope form of the equation, the equation should evaluate to ...

... 0 = 0

This is only true for point (-16, 8) using the equation of selection a).

Happily, we also find that point (4, -2) satisfies the equation.

... -2-8 = -1/2(4+16)

... -10 = -1/2(20) . . . . true

The appropriate choice is ...

... a.) y-8 = -1/2(x+16)

Brenda is building a square fence. She places a fence post at (─3,2). What is the location of the post (in which quadrant) that
Fynjy0 [20]

The post is on the first quadrant at the coordinates (3, 2).

Step-by-step explanation:

Step 1; First we need to determine which quadrant the point (-3, 2) is on. The coordinate has a negative value of x which denotes it could be located on either the second or third quadrant. The y coordinate has a positive value so out of the second and third quadrant, it is located in the second quadrant.

Step 2; The fence post is reflected over the y-axis which means the coordinate values remain the same but the symbols are in accordance with the first quadrant. In the first quadrant, both x coordinates and the y coordinates are positive. So the co-ordinate for the reflected fence post is    (3, 2).
